Massachusetts eighth-grader creates seizure detection device, earns national honor
At first glance, Sarah Wang is just like any other eighth grader, busy with school, sports and friends at the Pike School in Andover. But behind the scenes, she's an inventor, working on something that could save lives.
"I love academics, I love writing, I love science, I love history, I love everything," said Wang. "I would say I'm just someone who's curious and I really want, in the future, I want to innovate."
It's that curiosity that changed everything and inspired her invention.
"Two years ago, I was visiting my grandparents in China and my grandmother has epilepsy," said Wang. "I didn't know that before but she had a seizure and I didn't know what was happening, I was really shocked because she was unconscious."
This moment turned into months of research, learning about epilepsy, seizure detection and why many products just don't work.
"I found that a lot of these solutions for seizure detection, either they're too expensive, they're not adjustable, they're not comfortable," said Wang. "I think I could turn Hand Band into something greater."
So Wang built Hand Band, a wearable device that detects seizure-related hand movements and alerts caregivers in real time.
"The spring vibration sensor, first it can detect the rapid hand movements and then it turns the rapid hand movements into an electrical signal that we can continuously monitor," said Wang.
Once that signal drops below a threshold, an alarm is sent via Bluetooth to an app, alerting the caregiver to the seizure. Now on her third version, Wang's improving accuracy, shrinking the size and even looking ahead to a patent.
"Something I want to do is take this to the next level and to make this into an actual product," said Wang.
Wang is going to have the chance to do just that. She was just in Washington, DC as a 2025 National STEM Champion.
"I was shocked because I didn't know that this could go this far," said Wang. "I immediately told my family, I called my grandma and I'm just really grateful for this opportunity."
Surrounded by more than 100 other
National STEM champions
, Wang said she left with even more drive to grow her project and her passion.
"Seeing people integrate other types of STEM stuff, like chemistry and physics, biology, it's inspired me to try to learn more in different fields of science," said Wang.
At the festival, Wang wasn't just showing off a device. She was sharing a mission, one that started with her grandmother and now inspires young innovators nationwide.
"If you see a problem, if you see something happening, just think about what you can do to help the situation," said Wang.

Curbee: Mobile Automotive Service Increasingly Makes Economic Sense
People have shown they're amenable to have meals, books and clothing delivered to their homes. Increasingly routine services for cars and trucks at a consumer's home is occurring. 'It's becoming much more of a thing,' Amit Chandarana, founder and CEO of Curbee, said in an interview. Curbee provides mobile service technology for auto dealers. Last year, the company moved to take its technology national. Traditionally, vehicle owners took their cars and trucks to dealerships, garages and other providers of service for such things as oil changes, tire rotation, battery replacement, and work related to recalls. The time needed for such services can vary. Vehicle owners either waited while tasks were performed, or arranged to have rides until such work was completed. Advocates of mobile service say it can be more convenient and save time for vehicle owners. What's more, vehicles are increasingly computers on wheels. They sometimes require software updates, similar to personal computers and smartphones. Such updates can be provided by mobile service units. Chandarana said mobile service is a way for dealerships to expand their service resources at less cost. Curbee estimates a dealership can start mobile service for about $20,000 per unit compared with $200,000 or more to construct a new service bay at the dealership. Auto dealerships have seen oil-change businesses take customers away. Drivers replace oil and other fluids at such outlets rather than go into dealerships. Mobile service operations from dealerships 'is a way to recapture revenue they had lost,' Chandarana said. For dealers, vehicle service 'is the most stable part of the business,' he added. 'Customers have the need to have this choice' whether to travel to a dealer or have such services performed at home, Chandarana said. 'The more consumers know, they request it, the more dealers provide it.' Curbee says it helps dealers 'reimagine pay plants, technician career paths, and operational workflows so mobile becomes a growth opportunity, not an overwhelming burden,' the company said in a statement.

Netflix (NFLX) Keeps Momentum with Strong Content Pipeline, Says Piper Sandler
Netflix Inc. (NASDAQ:NFLX) is one of the best big tech stocks to buy right now. In a late-July note, Piper Sandler analyst Thomas Champion maintained a Buy rating on Netflix and kept his price target at $1,500. Champion's positive stance is based on recent improvements in viewership trends and a strong content pipeline. The analyst argues that June's Nielsen's Top 10 Viewership data showed a solid rebound in Netflix's audience numbers after a period of softness. He linked the turnaround to the launch of popular titles such as Ginny & Georgia Season 3, Blindspot, and Squid Game Season 3. Netflix Netflix has a heavy slate for the second half of the year, with new seasons of Stranger Things and Bridgerton expected to draw in more subscribers and keep momentum going. Champion also pointed to growth in Netflix's advertising business as another potential revenue driver. According to the analyst, the company's subscriber and revenue targets remain within reach, and the combination of popular content and new monetization avenues supports the current bullish outlook on the stock. Netflix Inc. (NASDAQ:NFLX) is a global streaming entertainment service that offers a diverse array of movies, TV shows, games, and more, with unlimited viewing on internet-connected devices.
